Yes, @pgreenland has experienced this also, see:

> [@LMS srsRAN and LimeSDR-Mini v2](https://discourse.myriadrf.org/t/lms-srsran-and-limesdr-mini-v2/7854):

> Has anyone tried the LibreCellular / LMS version of srsRAN with the LimeSDR Mini v2? I’ve been using a LimeSDR-USB with it for some time now, which has been working flawlessly. Swapping out the LimeSDR-USB for the new LimeSDR-Mini v2 performance is exactly the same for 20 minutes (as measured with iperf between the UE and eNodeB. Connected directly via cables the UE is able to download at 75Mbit/s and upload at 50Mbit/s as expected). After 20 mins of iperf the UE is disconnected with a stream…

Based on which @Zack tested, but could not recreate the problem. I also wondered if time\_adv\_nsamples could have some part to play. I think the only way to try and tune this parameter may be by trial and error. Perhaps you could test after increasing and decreasing the value, over a number of runs to at each setting and calculating the average uptime.

Can you please provide details of:

- O/S version
- Lime Suite version
- srsRAN version

And how you installed the latter two, i.e. packages or from source. It would be good to try and recreate this. Thanks also for reporting the issue, it’s most helpful!
